llfiACHlNE FQR COATING FABRiCS.

SSPECIPICATION forming part of Letters Patent No. 392,779, dated November 13, 1888.

Application filed May 6, 1887. Serial No. 237,328. (No model.)

To aZZ whom it may concern:

Be it known that I, HENRY G. BUNCH, of Rahway, in the county of Union and State of New Jersey, have invented a new and Improved Machine for Coating Fabrics, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a perspective view of my new and improved machine for coating fabrics. Fig. 2 is a sectional elevation of the same, and Fig. 3 is a plan view of the same.

The invention willfirst be described in connection with the drawings, and then pointed out in the claims.

A A represent two parallel side pieces mounted upon the base B. The side pieces, A A, are tied together by the cross-piece O, and thus constitute the frame of the machine. The cloth to be treated is wound upon a roller, D, journaled to the front of the ma chine, and over this roller pass the cords to a, to which weights 1) b are attached, so that said cords and weights will serve as brakes to prevent the roller D from turning too easily. From the roller D the fabric is passed under the crosspiece E, thence outside of the crosspiece F, the outer surface of which is diagonally grooved, as shown at ff, to act as a tentering'bar to spread the fabric edgewise. From the cross-piece F the fabric passes over the cross-piece G, thence under the spreader H, thence over the cross-piece J, drawingroller K, and beater L. The cross-pieces E F are in the same vertical plane, and the crossbars G J, drawing-roller K, and beater L are in substantially the same horizontal plane, but above the cross-piece F, as shown clearly in Fig. 2. The spreader H is composed of a bar, h, of wood, and a plate, h, of sheet metal set in said wooden bar h, and is held at its ends in the arms h h pivoted to the inner surfaces of the side pieces, A A. These arms may be adjusted to raise and lower the spreader, and curved slots h are formed at the upper ends of the side pieces, A, to accommodate the gudgeons i i of the spreader, and to the outside of the side pieces, A, are secured by bolts 6 the notched or slotted cleats 7c, in which the said gudgeons are journaled, and the cleats 7a are slotted, as shown at a, so that said cleats may be vertically adjusted to raise and lower the spreader H, as circumstances require.

The drawing-roller K is a rough roller covered in this instance with sand-paper, so that when said roller is revolved it will draw the fabric through the machine. revolved in this instance by the cog-wheel d, secured to the gudgeon of the roller, and the cog-wheel d,journaled in the arm d and to which a pulley, d is attached. The arm d is attached to the side piece, A, by a bolt, d, which passes through a slot, (1, in the arm (1, so that the said arm may be adjusted longitudinally, and also pivotally, to suit the two gear-wheels d d to each other, and to throw the wheels in and out of gear.

The beater L is a square bar journaled in the sidepieces, A, and is revolved by the gear-wheel Z, which meshes with the gearwheel 01, so that when the machine is in motion the fabric will be beaten from the under side by the bar L to detach any superfluous gilding or other material with which the fabric is coated.

In use the fabric will be placed in the machine, as shown in Fig. 2, and the material with which the fabric is to be coated on one side only will be placed in the depression of the fabric between the cross-pieces G J caused by the spreader H, and only on one side of said spreader, as indicated in Fig. .2. Then the roller K will be revolved, which will draw the fabric slowly through the machine and cause the spreader to distribute the coating material evenly over the surface of the fabric. The heater L is at the same time revolved, which acts to detach the superfluous or loose coating material.

WVhen the fabric is to be coated with-a dry substance, the fabric will first be coated with glue, paste, sizing, or other suitable material, either by hand or by any suitable machine for that purpose, to which no claim is made.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is

1. In a machine for coating fabrics, the ten- This. roller is ICO tering-bar F, and the spaced bars J G, in com- F, and the shaft D, all arranged substantially bination with the spreader H, held between as described. bars J G and the roughened drawing-roller T K, and means f0r=rev01ving the same, substzur RY BUNCH 5 tially as described. Vitnesses:

2. The combination,with the drawing-roller F. E. G-UCKERT,

K and the spreader, of the ba'rs G, J, E, and J AMES TIOHBORNE.
